Terahertz Sources and Receivers for Science Applications and Test & Measurement Systems

Abstract

Solid-state sources and receivers are now available throughout the frequency range from 100 GHz to 3 THz. Although III-V MMIC amplifiers and Si-Ge technology are beginning to extend throughout this band, systems based on GaAs Schottky diodes still offer the best performance for most applications. These include a variety of important applications in science, and also test & measurement equipment for laboratory use, such as VNA frequency extenders. This paper will review progress in this important technology with emphasis on recent results and its application.
